Hey everyone, for those who have the Naish Thrust wind foil, what setting do you use for the rear stabiliser angle? Do you adjust it up and down depending on the wind strength?

I have mine about 1mm above the "mark" and works well, but just wondering whether its worth tinkering with.

Cheers

I like it to drive the main foil slightly down, so it lifts more slowly and sets back down with less effort. Flying up to quickly is my problem, in the gusty light winds we get.

* bump * now that we have our own forum. Should I fiddle with the angle or just leave it in the same place all the time?

It's amazing what 2 to 3 mm from neutral setting up or down does for the tuning of the Naish foil . the screw also can slip a bit.make sure it is done up tight.

I think it depends on the board you're using with the Naish WS1.

With my Isonic 121 - I was adjusting the rear wing for max lift but since I moved the Tuttle box forward 12cms I'm back to the neutral setting.
I now need less back foot pressure to maintain foil height and my body position feels a lot more relaxed cranking upwind.

Cheers guys. I'm using it with Exocet RF91 foil board.

Do other naish users adjust the angle based on wind strength or is it better to leave it once you find a sweet spot.

Once you find the sweetspot, leave the setup alone and compensate with you innate physical and mental abilities.

I have mine about 2mm up. Find that perfect for me. I also have my mast about 1.5cm forward of centre. I spent a day doing micro adjustments and that seemed to be best for me. When I've changed it down for higher winds I just don't have the control.

I think it has a lot to do with your natural stance. Done sailors will be more front or rear foot.

also depends a lot on your sail and the lift being generated.

I generally have the rear wing trimmed flat or slightly down (-ve lift). As LeeD suggests, getting the thing flying is not the problem - controlling it is. Have also found the mast base setting makes a big difference to how you can pump the board onto the foil. Keeping it back seems to make it a lot easier. Have sailed the Naish and the Slingshot. Naish definitely easier and more controllable. Slingshot has slightly more performance.

And I'll add in higher winds (over 15 knots) I would go even more negative with the rear wing setting. But in most cases, I don't bother to foil in 15+ knots. I'll get out the conventional gear. 15+ I find the foil starts becoming a real handful and I'm down to a 4.2 to keep it under control.
And yeah gavnwend, I have had the screw adjustment for the back wing slip too.

Interesting re. the negative setting, what board are you using?

I've found it quite fun in 20 to 25 knots - as a means of gliding over the chop and getting upwind easily to explore.
Pretty stable and relaxing cruising with a 5m wavesail, just occasionally having to spill wind in the gusts.

Hey Azymuth. I'm using the Naish board (Hover 122) which came with the foil. It's interesting with wind strengths and how different sailors cope. I'd be down to a 3.7m in 25 knots.

It's a technique thing.. I can indeed fly with 3.6 in 25 knots, but did 8.6 on the big board today in gusts 25. Just point higher upwind, deeper downwind, possibly take your backfoot out of the strap across the wind and make sure your harnesslines are set correctly (huge difference) as for stab settings, never touched it, moved my footstraps instead.

Water state has a bearing too.
Where I sail, Berkeley Ca., if the wind starts to reach 18 or so mph, the windswells rise to mast height [70cm, Naish setup], I'm on 4.0, and I could be windsurfing on 85 liter boards and jumping on a 5.3 sail.
Worse, since March, almost every day continues to rise past 22mph breezes, and of course, unpredictable in gustiness hi and low.
Perhaps some day in the future will be a day of 7-15 mph. I haven't seen it without it rising to 22 or dropping below 8 by the time I rig.

i have the naish hover and my set up is foil as far back as possible with the rear wing lifted up about 1 mm and the mast track back from centre in the mast box and it all works a treat , have moved it so many times but still come back to this setting sail size dosnt seem to make any difference so at the moment just using a 5.8m free ride sail .

Thanks.
Tried stab with about 1.5mm lift, but it'd drop faster than rise so set stab at .5 mm lift and seemed more balanced up and down.
Was using mast track just back from center but just moved it mostly all the way back.
Foil set 2" back of recommended setting by using the forward holes.
Always seem to fly too easily.

It depends on your weight too. If you are heavy you need to either ride faster to get the lift or set the Stab to help you get lift which leads to control problems at speed. I found it was best set fully down for me on the WS1 but on my XL Surf it worked really well at 0.5 to 1mm (the width of the line I took as 1mm). The Naish system is really cool in so far as it gives you super amounts of adjustment, especially when you take in to account the ability to move the foil forward and back in the box and move your footstraps..
Having now been foiling for a year and pretty competent I actually wish I had just always kept it in the neutral settings with foil in middle of fin box and just learned to sail. I tried so many settings that in the end I didn't know if it was me or the kit that led to an improvement or a stagnant session.

You need to make sure the stab it tight. Mine did fully deflect a couple of times which led to a few runs of wild bucking Bronco and another of slalom sailing unable to lift off the water.

My biggest problem was control in pitch. I was having to constantly control the pitch which seemed too sensitive leading to constant touch downs.
I tried another make with a longer fuse and it was instantly better and i foiled for 100's of meters without touching down. Im 6'1 and 110kgs so I think the fuse length of the Naish is too short for me. All stab adjustments just added to the twitchiness for me. Ive now gone over to another foil brand and seeing progression every session. I cannot fault the Naish system for quality and user friendliness but I just think i was outside the design abilities for what I wanted. I needed to be doing 15 to 20 knots to foil when I wanted to be doing 10 to 15 knots.

Thanks for sharing your experience. I have watch your videos too.
At day 21, I'm still searching for pitch stability in our mostly 7-22 mph breezes. Usually with 4.0 sail.
Most runs, I have to jump out of straps and slog for hundreds of feet 2-4 times each run and pump onto a plane that many times again.
If the board planes, the foil lifts.
I have never foiled in winds of 7-15. If it's that light, it's more like 3-15, which constantly changes.

Day 29, getting long stable flights as long as 22 mph gusts don't come when I"m on 6.0.
Practice might be more important than settings.
Still setting board down, start to bear downwind, board lifts onto foil, flip sail and foil out, NOT a foiling jibe
Been setting the board down when overpowered, but it's survival and slow compared to foiling..

I'm wind foiling a JP 7' Sup Foil board and I love the 1 mm of + lift setting. I've found that shifting to the -1 mm setting really helps if I'm over powered or practicing jibes or you want to put the petal to the metal.

Regardless of all your settings (mast, foil, rear wing) if the foil is prematurely trying to lift and bucking, that's a no win.
Also for pumping up on foil, it helps if the board stays flat till you hit minimum velocity before you kick her up.

I really like the adjustable system as well. Kinda like the Abracadabra...yes there's a little extra weight but so easy and time saving to transport.
